REGISTER.

SPECIFICATION forming part of Letters Patent NO. 473,751, dated April26, 1892.

Application filed July 14, 1891. Serial No. 399,500. (No model.)

To a/ZZ whom t may concern,.-

Be it known that I, THEODORE C. HOWE, a citizen of the United States,residing at Genesee Fork,in the county of Potter and State ofyPennsylvania, have invented a new and useful Register, of which thefollowing is a specification.

This invention relates to stoves and furnaces, and more especially tothe registers used in connection therewith; and the object of the sameis to produce certain improvements in devices of this character.

To this end the invention consists in the details of constructionhereinafter more fully described and claimed, and as illustrated on thesheet of drawings, wherein- Figure l is a plan View of this improvedregister partly closed. Fig. 2 is a section across two of the joist-sand the flooring and the ceiling of the room below, showing the dampertherein as partly closed. Fig. 3 is a central longitudinal section ofthe entire device. Fig. 4L is a horizontal section through the center ofthe joists.

Referring to the said drawings, the letters J J designate the j oistsupon which is mounted the ooring F, and to the lower edges of which issecured the ceiling C of the room below.

S is an ordinary stovepipe passing vertically through the ceiling andiiooring midway between the joists, and the products of combustion froma stove or other source of heat are directed into the lower end of thispipe and are led from the upper end to a suitable exit, as will beclear.

R is a register let into the iiooring between the joists and surroundingthe stovepipe S, and G is a grating let into the ceiling immediatelybelow the register, as seen in Fig. 3, and also surrounding the pipe S.y The register and grating are connected by a metallic casing M', sothat they may be withdrawn together from position. The registercomprises a lstationary upper member provided with the usual openings O,and a movable lower member M, oscillating around the stovepipe andprovided with openings adapted to register with those in the stationarymember when the movable member is properly turned. To effect thismovement a rod R is pivoted at P to the casing M and is pivotallyconnected at K to the movable member, its extremitiesv moving in slots Ain the register and in the grating and projecting slightly beyond thesame in order that they may be operated by hand. The products ofcombustion at all times pass through the pipe S, and the heated airaround the pipe in the room below passes through the grating at alltimes but can only pass into the room above when the register R isopened;

The letter W designates the end wall of the casing l between the floorand ceiling and between the joists beneath one edge of the register, sothat what heat passes through the grating will have no exit in thatdirection. Beneath-the other edge of the register in the other end wallW', Ilocate a damper D,whose movable member m turns beneath lips L onthe stationary member, the latter in this case being the wall W and thetwo members having openings O similar to those in the register. Securedacrossthe center of the movable member m is a rod fr, embraced by lipsor tongues Z on said movable member, and the extremities of this rodproject through slots a in the edge of the register and the grating at-right angles to the slots A. Then the register R is closed and the heatpasses through the grating G into the space below the register, the wallWV prevents its escape in one direction, but the damper D may be openedto permit it to pass in the other direction through the flue formed bythe two joists, the floor, and the ceiling. This flue may communicatewith the chimney or with any suitable eXit.

It will thus be seen that an operator in either the upper or lower roommay open or close the register and the damper. When both are open, aportion of the heat in the room below passes into the room above. Whenthe damper is closed and the register open, all the heat that passesthrough the grating passes also through the register, and when thelatter is closed and the damper is open all the heat passes into theflue,while when both are closed there is no result other than would beproduced by a solid ceiling.

If desired, various minor changes may be made without departing from thespirit of my invention.

The grating and register and possibly the damper are preferably ofcast-iron, although the materials, size, shape, and proportions of partsare not essential.

an operating-rod connected to the damper and having its ends extendingthrough the upper and lower sides of the box, substantially as2specified.
